Application filed October 9, 1928. Serial In. 140,48t

This invention relates to machines for performing upon paper or otherfabric, and more particularly to improved means for punching aperturesin paper or perforating 5 paper and for perforating and punching paperat the same operation.

In some businesses, such as the business of supplying stationery for usewith manifolding machines, the paper strips after being in printed uponare punched and perforated to provide apertures in each form of thestrip and perforations are provided between adjacent forms. Theperforations and the punch holes cooperate with each other in themanifolding machine, for the punch holes determine the tearing-oifpositions of the strips while the perforations define the tearing-offpoints on the strip and assist in the tearingoif operation. Hence, it isextremely desirao able to have the punch holes and the perforationsalways accurately placed with respect to each other.

I Heretofore, the operation for punching the apertures in the paper andthe perforating operation were performed separately at points remotefrom each other, and this, due to stretching of the web and mechanicalslippage and misadjustment, has caused considerable difficulty, for insuch case the perforations and the punch holes would not have theirfixed desired relationship with respect to each other.

An object of the present invention is to provide means whereby the punchholes and the perforations for each form may be made concurrently and ata single operation so that they will always have the desired fixedrelationship. This is accomplished by providing a unitary structure forsimultaneously punching and perforating each form.

The problem which has been solved by the provision of the meansdisclosed herein, was rendered more diflicult because, while the desiredrelationship between the punch holes and the perforations must remainfixed for a particular job, yet, the distance between the perforationsand the punch holes is not standard. There are, however, two suchdistances which are practically standard.

Accordingly, the present invention provides a perforatin device and itssu port in such a way that fiy reversing the per orating device on itssupport, either of these two standard distances between the perforationsand the punch holes can be had.

A still further object of the invention is the provision of means formounting the crforatlng unit upon its support so as to old 1t to andprevent it from moving upon the support.

And a still further object is the provision of means for adjusting theperforating de- 'vice so as to vary the extent of movement of theperforator which consequently varies the width of the minuteperforations.

And yet another object is to provide for universal adjustment of thepunching units relative to each other and as a whole parallel to andtransversely of the direction of travel of the printed web.

Other objects and advantages will hereinafter appear.

In the accompanying drawings which illustrate the form of the inventionat present preferred- 75 Figure 1 is a schematic side view of a printingpress showing the device of the present invention as applied thereto.

Fig. 6 is aplan view of a portion of a web of paper showing theperforations and punch through the line 99 of Fig. 3, showin thepunching and perforating unit adjuste' according to the standard shownin Fig. 6.

Referring now to Figs. 1 and 2 so that a suficient understanding of theprinting ress may behad to a preciate and .understan the application oft 0 present inventlon thereto,

,a web of unprinted paper is led from a supply roll 21 over a guide 22under a dancin roller 23 between guide rolls 24, 25, 26 an?! 27 and overa platen 28 where the paper is printed with the desired form. From theplaten 28, the printed web 29 is guided over aguide roller 30 to thefeed mechanism 31 located at the delivery end of the press. The

guide rollers, platen and feed mechanism are all mounted on the bed 32of the press.

Between the guide roller 30 and the feed mechanism 31, the presentinvention provides a punching andperforating unit 33, having a baseportion 34 and ahead 35.

Referring to themechanism shown in Fig. 2, the bed 32 of the presssupports a main drivesha-ft 36 having a pitman 37 connected toa movablehead 38 for the press which carries the type form 39 into cooperationwith the platen 28. The main drive shaft 36 is provided with a cam 37a,for cooperation with a' cam'arm 38a mounted on a square shaft 390carried by bearings 40 in the bed 32. I

- The uare shaft 39a is provided with an' arm 41 s idabl mounted'thereonand adaptedto turn wit the shaft. This arm 41 carriesja universal 'oint42 connected to a link 43 which in turn asa universal joint 44 connectedto an arm 45 mounted on an operatin shaft 46 of the combined perforatingan punching head 35 which will be described hereinafter. v

Thus, when the main drive shaft 36 operates, the type form 39 is broughtinto engagement with the platen 28, and in the proper sequence the shaft46 is rocked by its connetion with the arm 38a and the cam 37 a on themain drive shaft "36.

Heretofore, perforation of the forms was accomplished at the same timethat the forms meoaoee were printed, the perforating rules being carriedin the printing form 39, and the punching device was located somewherebetween the guide 30 and the feed mechanism 31 With this previousarrangement, there was a large free stretch ofprmted webs 29 between thepunching device and the platen which frequentl caused the registration,or proper s acing etween the punch holes and the per orations to varSuch variation was, of course, extreme y undesirable and troublesome,because in some manifoldin machines the tearing-ofi' point, was definebythe perforations while the stopping of the strips 1s predetermined bythepositions of the punch holes.

The present invention avoids these disadvantages by providin means forconcurrently perforating an punching the strip and performing both theseoperations at the same place in the travel of the printed web 29.

Referring now to Fig; 6, the printed web 29 is provided with prlntingfor the separate forms 47. After passin through the punching andperforating devlce the head of each form is provided with punch holes 48and perforations 49, the punch holes being used for aligning and paperstopping purposes in the manifoldin machine and for binding purposesafter t e forms have been written upon, and the perforations 49 beingutilized to facilitate the operation of transversely folding the stripswhen making a packet and severing of the strip into form lengths whenbeing used. The distance Y (Fig. 6) between the centers of the punchholes 48 and the line of perforations 49 represents a standard dimensionfor a particular kind of work, and as stated, it is extremely importantthat this distance .be kept accurate and constant in all the forms sothat the tearing-01f operation will surely take place along the line 49and not either behind or ahead of it.

In Fig. 6, the leading form 47 is shown as perforated and punched, butthe other two forms are unperforated and represent the form of the webbefore it reaches the punchin and perforating device 33.

ile the distance Y, shown in Fig. 6, is standard for a particular kindof work, there is another standard distance for different and importantkinds of work. This is shown in Fig. 7, in which a distance X is leftbetween the line of perforations 49 and the punch holes 48. Thedistances X and Y being correct for the majority of manifoldin machinesthe production of either kind 0 work in asingle printing press isgreatly facilitated by the present invention by the provision of meanswhereby the mere operation of reversing the perforating device willcause either dlstance X or distance Y to be provided between theperforations and the punch noles. Hence, according to the present invention, it is no longer'nccessary to expend considerable time and laborin setting-up preparatory to the production of the different kinds ofwork.

Referring now particularly to the punching and perforating unit 33,reference being had to Figs. 3, 4, 5, Sand 9, the present invcntionprovides a frame which is mounted on a base 51 held to the bed 32 of thepress by releasable clamp 52, the bed of the press at this portionconstituting rails and the clamp 52 permitting the bed of theperforating and punching unit 33 to be slid along to desired position.This longitudinal adjustment of the punching and perforating unit 33 isprovided for the accommodation of forms of different lengths and permitsthe punching and perforating unit to be located at the proper point foroperation in con-. nection with all sizes of forms within the limits ofthe press. To enable it to operate the head 35 in the various adjustedpositions referred to, the arm 41, which operates the shaft 46 of thepunching and perforating unit, is allowed to slide on the square shaft39 being fixed in the desired adjusted position by means of a set-screw410:.

In order to permit lateral adjustment of the frame 50 of the punchingand perforating unit, cooperating guides 53 and 54 are provided on theframe 50 and the bed 51 respectively, and an adjusting screw 55 havingits head 56 anchored to the frame 50 by a saddle 57 and itself mountedin an extension 58 on the bed 51 moves the frame 50 either to the rightor left as seen in Fig. 3, according to the direction in which it isrotated. The adjusted screw 50 is locked in desired position by means oflock-nuts 59.

Thus it will be seen that the punching and perforating unit 33 may beadjusted either longitudinally of the press or laterally of the press tobring the punching and perforating unit into the desired location withregard to the printed web 29.

The frame 50 of the punching and perforating unit 33 has upwardlyextending arms 60 for supporting the movable portions of the punchingand perforating unit and also the operating shaft 46. The movableportion of the perforating and punching unit comprises. a head 61 havingangular bearings 62 adapted to ride in V-shaped grooved bearings 63inserted in the extending arms 60 of the frame 50. It is upon thesebearing surfaces 62 and 63 that the head 61 rides up and down inoperating to punch and perforate the paper. Movement is imparted to thehead 61 for this purpose by means of an eccentric cam 64. This cam 64 islocated in a saddle or yoke 65 having upper and lower bearing surfaces66 and 67 for engagement with the cam 64 so that as the shaft 46rotates, the head 61 is reciprocated riding on the bearings 62 and 63.

' The punches 68, for producing the punch holes 48 are mounted in anangular bar 69 shaped to fit snugly against part of the under-side andpart of the side of the head 61, see Fig. 9, with the top of the punch68 in contact with the under-side of the head 61. There is an angularbar69 for each pair of punches 68 (see Fig. 5) and this bar isadjustable along the head 61 transversely of the direction of feed ofthe web, and a clamp 7 0 located in an under-cut groove 71 in the head61. The clamp comprises a screwthr-caded portion 72 and a flanged nut 73by means of which it may be tightened to firmly draw the bar 69 againstthe head 61 and hold it in place. Since the under-cut groove 71 extendsthe entire way across the head 61, the bar 69 for each pair of punches68 may be brought into the desired position with regard to the printedmatter of the form 47 merely by loosening the nut 73 of fhe dclamp 70and sliding the bar along the iea This transverse adjustment of thepunching device with regard to the head 61 and with regard to each otheris extremely advantageous, for frequently the punch holes 48 ofdifferent forms are located in different positions laterally withrespect to each other, and hence in a single operation forms ofdifferent characters or Width may be punched. Then, if when setting upthe press the position of thewvb with respect to the punches is notquite right, the entire gang of punches may be moved laterally bymanipulation of the screw 55.

Below each set of punches 68, there is provided a punch block 74 havingcutting dies 75 for cooperating with the punches 68. These punch blocks74 are adjustable in the same manner as the bars 69 for the punches 68,and, of course, in making the adjustment care must be exercised that thedies 75 in the punch blocks 74 are located beneath the punches 68 in thebars 69.

The perforating operation is performed by a perforating knife 76 held ina bar 77 extending transversely across the frame 50 so as to operateupon the entire width of the web 67. The bar or frame 77 for theperforator 76 is shaped to fit closely against the head 61 and thebottom of the angle bar 69 for the punch and is held in this positionagainst movement laterally of the unit by means of wing-nut 78 carriedby screw 79 threaded in the head 61.

In order to adjust the bar 77 which carries the perforator 76 verticallyfor the purpose of increasing or decreasing the depth of theperforations or to make the depth that desired, the bar 77 has threadedin it an adjusting screw 80 having a finger-piece 81 located above asaddle 82 and a disk 83 located below .the distance between theperforator the saddle 82. The saddle 82 is screwed into the head 61 soas to have a fixed positiontherein. When it is desired to raise or lowerthe perforating unit, the win nuts 78 are loosened to rmit free up-an-down movement allowed by the elongated slots 84 in the bar 77 throughwhich they pass, and then the finger-piece 81 is rotated to move the bar77 up-and-down as desired. When the perforating unit has been properlyadjusted, the adjusting screw is locked in desired position by alock-nut 85 and then the wing-nuts 78 are secured in place to hold theperforating bar as adjusted.

The perforator 76 is held in adjusted position firmly against the bar 77in a longitudinal groove 86 therein by means of a wedgeshaped bar 87secured in place by screws 88 which carry the wedge-shaped bar up to thegroove 86 and. firmly hold the perforator 76 therein against anypossible movement. It will be noted that the perforating unit 76 is notlocated directly in the center of the bar 77, and also that the bar 77is made exactly the same on both sides. The groove 86 in the bar 77 isso located that when the bar 77 is placed on the head 61 in the positionshown in Fig. 9, the punch and perforating unit is set up to provide thedistance Y between the centers 0 the punch holes 48 and the line ofperforations 49. When, however, the wing-nuts 78 and screws 79 areremoved, the bar 77 may be taken off the head 61 and reversed, thusbringing the perforator 76 to the position shown in Fig. 8 where 76 andthe punches 68 is the same as the distance X. Hence, when the punchingand perforating unit is being set up the bar 77 is so placed on the head61 that the perforating member 76 is either in the position shown inFig. 8 or in Fig. 9, according to whether the distance between the punchholes and the perforations is to be distance X or distance Y.

It will be noted that when the screw 88 is set in place, it draws thebar 87 upwardly and hence jams the perforating unit 76 firmly againstthe side of the longitudinal slots in which it is located.

A block 89 which is located under the perforating unit 76 and acts as apurchase for the paper during the perforating operation is mounted onthe frame 50 by means of screws 90. The frame 50 is provided with twoholes 91 and 92 into which the screws may be set. When the frame 77 forthe perforator is set up, as shown in Fig. 8, the

screw 90 is placed in the hole 91, and, in this position, the apertures93 in the block-89 are directly beneath the perforating device 76. When,however, the perforating device 76 is set in the position shown in Fig.9, the screw 90 is placed in the hole 92 in the frame 50, so that theapertures 93 will be then directly under the new position of theperforating I device 76.

For the purpose of causing the perforatgr to be withdrawn from theperforations 1n the web 29, which the perforator makes therein, astripper bar 94 mounted on guide screws 95 sliding in clampin bar 87 isprovided with a s ring 96 whic causes the stripper bar 94 to normallylocated below the lower edge of the perforating device 76. When the head61 moves downwardly to cause the punch and perforator to operate, thestripper ar 94 engages and firmly holds the web 29 against the block 90while the perforating device 76 pierces the paper. As'the head 61 rises,the perforating device 76 is withdrawn from the perforations in thepaper while the stripper bar 94 is yet in contact with the block, andhence the perforating device 76 is completely withdrawn from the paper.During the subsequent upward movement of the head 61, the stripper bar94 is removed from engagement with the paper b reason of the engagementof the heads 9 of the guide screws 95 with the bottom of the slot inwhich they are located.

The punches 68 are likewise provided with means for assuring that theweb 29 is not drawn upward with the punch. For this purpose, they areprovided with strippers 98 mounted, as shown in Fig.8, on guide pins 99and are provided with springs 100 for holdin the stripper bar 98 inoperative position. The guide pins 99 are mounted in the angular block69 which carries the punches 68 and each block 69 has its own stripper,so that no adjustment of the stripper need be made when adjusting theblock transversely of the direction of feed of the web. The strippers 98operate in the same manner as the strippers 94.

It will thus be seen that the present invention provides universaladjustment for the punching and perforating device and provides a simpleand easy means of producin diiferent distances between the punches andthe perforator, so that two standard kinds of work can be done on thesame printing ress with very little labor and time neede for shiftingover from one kind of work to the other, and no special set-up operationbeing required.
